Mechanism and rheological characterization of MDI modified Wood-Based Bio-Oil asphalt

The application of waste wood-based bio-oil in asphalt binder has illustrated many performance advantages for the pavement. However, the introduction of bio-oil to asphalt binder has challenges associated with poor high-temperature performance. To address this matter, the liquefied 4,4′-diphenylmethane diisocyanate (MDI) was utilized as an additive to enhance the high-temperature performance of wood-based bio-oil asphalt (WBBA), while not...
